A vector quantity is one which has both magnitude and direction. The direction of current is opposite to the flow of electrons. Electric current has both magnitude and direction so ideally it 'should' be a vector.
WebSep 11, 2024 · The dot product is the product of two vectors and produces a scalar. From a component view the main rules are that the dot product of same unit vectors are equal to one and different unit vectors are zero. So i ^ ⋅ i ^ = 1 and the like and i ^ ⋅ j ^ = 0. The dot product the vector A and vector B: (14.5.6) A → ⋅ B → = A x B x + A y B y + A z B z
